PROBLEM to import NTAG I2C PLUS middleware

Hi to all,I'm working with MKL33Z64 and MCUxpresso IDE v10.2.1 I have to interface the NT3H2111 NTAG I2C plus device by I2C in my own board.I downloaded the SDK "SDK_2.4.1_MKL33Z64xxx4" and inside of it there is the folder "Middleware" with"ntag_i2c_plus" code.

My focus is to use the "ntag_i2c_plus" middleware code in my own project like a library.

In all the Evaluation board software examples the inclusion of middleware files is already in.

If I have an already existing own project, what is the simple way to use the middleware files?Somebody have any suggestions, please?
